I live in a society where my national healthcare gave such support in my said example clearly showed that support was there and actually sufficient and funded through the government otherwise sadly this individual who was part of my society, wouldn't have been able to live up to a point where his functions descended into only blinking. I think you missed the point of the example entirely so I will break it down. They received monetary funds to keep a household afloat and so the wife could take care full-time. They clearly received medical extras such as breathing apparatus, colostomy bag and more as a means to prolong their life and not suffer though clearly they did to a point where over a period of time at the lowest of the low point, they expressed to die.
But even after all that support and was in such an extreme set of conditions that he wanted to die, that's acceptably extreme. Where a man who could physically do anything for most of his life was basically left to sit in a chair that couldn't feed himself, go to the toilet in a controlled state, couldn't dress, can't express emotions verbally or physically even with facial expressions, could hardly breathe... Even less than a new-born child. Don't you agree that's extreme stress and distress on any adult's mind?
Stephen Hawking is not a very good example at all. He felt his life could continue personally though this said individual clearly stated several times in sound mind, he was ready to die and had to kill himself in a desperate attempt to acknowledge his plea.
Stephen Hawking had government funding too like the said individual, perhaps less too but Hawking had help from outside resources too, that wasn't funded through my society which to make it help I'm English, the said individual is English and so is Stephen Hawking.
Stephen Hawking came to live with his disease at a time where medical technology wasn't as advanced as now however, he had people around him whom were able to help him surpass his limitations through genuine love, attention and know-how. For example, his first machine that allowed him to talk was made by one of his carer's engineering husband who built it by using I believe parts from radios, telephones and the voice came from a part he got from his workplace. Things like that are not on the agenda of support for most places, most likely won't be either because technologically we aren't a point of mass production in that vein.
Just so you know the technology we use on smartphones is what Stephen Hawking uses. That tech made for Hawking was later adapted to be part of smartphone capabilities, and it was made by a variety of people over the years including from the military and university students, just because they wanted to help Hawking. Not everyone gets that adoration or help. Hence the bad example.
